How Vacuum Cleaners Work and Why you Need One

Vacuum cleaners are devices that clean by sucking up dirt and dust. A vacuum cleaner works wonders when it comes to decreasing indoor air pollution. Bits of paper, pet hair, dust mites, hair, and other waste matter are sucked up from curtains, carpets, floors, and upholstery.

It is an essential appliance in today’s home. Vacuum cleaners help keep offices and homes hygienic and clean. It simplifies the chores and saves us a great deal of time.

Although the essential principle involved in vacuum cleaner operation is the same, there are several factors that cause these devices to vary to a degree.

Think about your needs before purchasing a vacuum cleaner. If you have a large home, get a vacuum cleaner with the highest power output. On the contrary, less messy and smaller houses, on the other hand, would be better served by purchasing a small vacuum cleaner.

Components of a Vacuum Cleaner

The vacuum cleaner’s mechanism is dependent on a few key components. There are six main components of a conventional vacuum cleaner. The following are the details:

  • A fan
  • A housing for all the other components
  • An intake port
  • A porous bag
  • An exhaust port
  • An electric motor

An exhaust port

You’d assume the cleaner would stop sucking after a couple of moments because it couldn’t possibly take that much air into such a little space, but this is not the case.

The cleaner comes with an exhaust port that helps to release air to the other side so it can keep whisking dirt into the canister. The motor can run thanks to the exhaust port being properly sealed.

Electric motor

An electric motor is at the heart of a vacuum cleaner as it helps spin the fan. Both parts work by sucking in air and any tiny particles in it. After it sucks in the particles, the cleaner sends them out the other side into a trash bag or a canister.


The size of the intake port and the electric motor’s power determine the vacuum cleaner’s power. The intake section sucks up the dirt. The suction power created is proportional to the size of the intake.

When the same volume of air is forced through a smaller passage, the air moves speedily. Models with narrow, compact entry ports suction much faster than larger ones.


So, does the exhaust port pump dirt-laden air into the living room? You will be pleased to discover that the working mechanism of a vacuum cleaner ensures this does not happen.

Yes, the air drawn in by the vacuum cleaner might be dangerous if it is released into the environment. After all, the air that the machine sucked in was full of grime and dirt. The air can also cause serious lung damage if inhaled in big amounts.

The machine passes the air through one or more fine filters to prevent this. Before venting the air to the other side, the filters remove fine particles and practically all the dust.

Typically, a HEPA filter is used. After the air passes through this filter, you can now breathe clean air once more.

What Happens When the Vacuum Cleaner is Plugged in?

This is what happens as soon as you switch on the vacuum cleaner:

  • The motor is powered by an electric current. The fan, in turn, is spun by the motor. The blades of the fan are angled. The blades resemble those of an aircraft propeller.
  • The fan blades move air toward the exhaust port as they rotate.
  • When the fan blades propel air particles forward, the density of the particles increases in front of the fan and decreases behind it.

Consider how a straw works to learn how a vacuum sucks the debris up. Using a straw to drink creates a negative air pressure due to the suction. This pressure is lower than the surroundings.

What affects a vacuum cleaner’s performance?

After learning how this machine operates, it is time to think about the factors that influence its operation. In many ways, the same considerations that go into purchasing a vacuum cleaner apply here.

By establishing a pressure difference, vacuum cleaners suck up debris and dirt. The air stream passes via the filter, which leaves all debris and dirt behind.

Fan speed and motor power

The vacuum cleaner should have strong suction in order to work flawlessly. This is determined by a number of elements, which include the vacuum cleaner’s fan speed and the condition of the air path.

A fan’s speed is critical to providing the needed amount of suction. It is reliant on the motor’s power to rotate the blades. You will enjoy greater efficiency if  the motor is powerful enough to rotate the blades at the desired speed.

A motor with less power, on the other hand, will not be able to provide an adequate fan speed. Aside from that, the air passageway or intake port must provide a clear route for the air stream.

Clear air route

The air particles will encounter resistance if debris or dirt is clogging this passage. Therefore, the speed of air will decrease. Because of that, the friction caused by moving air weakens, which makes dust collection impossible.

Additionally, while generating a considerable quantity of suction and air pressure, the size of the intake port is important.

In most circumstances, the vacuum cleaner’s fan speed remains constant. The amount of airflow remains constant as well.

This also implies that the vacuum cleaner would pass the same amount of air regardless of the intake port’s size. But, when the intake port is reduced in size, the air particles move very quickly.

When the airspeed goes up, the pressure of the fan’s front part drops, increasing the suction. In general, people like to use narrower intake ports when they clean large debris and dirt particles because they provide more suction.

Why do you need a vacuum cleaner?

These machines have a plethora of benefits, one of which is that they are a popular tool for helping to clean dirt and dust in all types of homes or establishments. Vacuum cleaners are regarded as one of the most useful household tools ever invented.

Apart from cleaning debris, they also offer an effective way of dusting the floor, reducing the risk of allergy flare-ups, and improving air quality.

Dirty beds, upholstery, and even carpets trap a variety of respiratory irritants, including dust mites, pet dander, and everyday dirt and dust. They can induce irritating coughing, sneezing, runny noses, and even worse when breathed in.

A vacuum cleaner usually comes with a HEPA or other filters that helps block and eliminate allergens.

Experts recommend that people vacuum their houses once or twice each week to combat the awful allergies. They should also use a vacuum cleaner that is of excellent quality and efficiency. Vacuuming helps prevent small particles from re-entering the air, which lets us freely breathe.

If you have a pet, it’s not unusual to see your favorite rug or carpet covered in a pet’s hair. It is, without a doubt, a highly irritating issue and one that adds to the risk of people who suffer from allergies.

Luckily, the vacuum cleaner is adept at removing pet hair that has become trapped in the carpet pile. This is due to the suction power of vacuum cleaners. It aids in getting rid of pet hair and odors from the carpet.

Recover small objects

Grab your vacuum if you’ve dropped something small behind a hard-to-move piece of furniture, such as a screw, nail, or earring.

Secure a piece of old pantyhose or mesh over the crevice tool’s end with a rubber band. The vacuum’s suction will trap the lost object against the mesh, allowing you to get it back. You should aim for the lost object.

Cleaning Kitchen appliances

  • Use the vacuum to remove any ashy residue after an automatic oven cleaning cycle.
  • Use the vacuum to get rid of crumbs from unplugged toaster ovens and toasters to avoid small fires.
  • Using the vacuum crevice tool, de-crumb the gaps between countertops and appliances. You can prevent insect infestations by keeping crumbs under control.
  • With a vacuum cleaner, get rid of dust from the refrigerator condenser and coils. The refrigerator will run more efficiently and maintain cooler, more consistent temperatures.


One of the advantages of vacuum cleaners that most consumers aren’t aware of is versatility. The machines have become more diverse and multipurpose, making them an appealing investment.
